7 SPREADER;

To all whom it may concern:

Be' it known that I, WILLIAM H. BINDER, a citizen of'the United States,residing at San Luis Obispo, in the county of San Luis. Obispo, State ofCalifornia, have invented certain new and useful Improvements inSpreaders; and I do declare the following to be a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, and to the characters of reference marked thereon, which forma part of this application.

This invention relates to improvements in sand and gravel spreadersadapted for use in connection with wagons or trucks designed forcarrying sand or gravel for distribution over highways or similarplaces. The object of the invention is to produce a spreader which willkeep the sand or gravel in continual motion and equally distributed overthe surface of the street or highway or other places in an even andproportionate manner and in such quantities as may be desired. Also theinvention embodies means for evenly spreading material along theshoulders of the road which is very essential in the making up andkeeping up of highways. The invention is designed to do away with thenecessity of manually spreading the sand or gravel as is now the mostcommon practice. My improved structure is attached directly to the wagonor truck and the distributing shaker is operated by being connected withany suitable driving means connected with the wheels or driving parts ofthe vehicle.

A further object of the invention is to produce a simple and inexpensivedevice and yet one which will be exceedingly effective for the purposesfor which it is designed.

These objects I accomplish by means of structure and relativearrangement of arts as will fully appear by a perusal o the followingspecification and claim.

In the drawings similar characters of ref erence indicate correspondingparts in the several views.

Figure 1 is arear elevation of my improved structure.

Fig. 2 is an end view of the same.

Fig. 3 is a detached fragmentary view of the distributing shaker used inconnection with the spreader.

Referring now more particularly to the characters ,of reference on thedrawings, my improved spreader consists primarily of a container 1 whichmay be suitably connected Specification of Letters Patent.

with a truck or wagon in any manner found most desirable. The front endof the container 1 is opened as at 2 to allow of the material beingfilled therein from the truck or wagon in any suitable way or manner.

The rear end of the container 1 is open and such open end is controlledby a slidable door plate 3 movable between guides 4 and 5. On the doorplate 3 are rigidly fastened bearings 6 movable vertically in slots 7formed in the side walls of the container 1. Arranged for sliding motionin the bearings 6 is a shaker rod' 8 having inwardly projecting shakerteeth 9. This shaker rod 8 as shown in Fig. 1 extends immediately alongthe lower edge of the door plate 3.

Reciprocating motion is applied to the rod 8 by means ofthefollowingstructure, namely: beveled gear 10 is suitably driven byanother beveled gear 11 which in turn' is driven by the sprocket wheel12, which sprocket wheel is connected by suitable chains to any desiredsource of power such as the jackshaft on a motor truck or any othersuitable driving means found desirable according to the form of vehicleused. A wrist pin 13 is mounted on the back side of the gear 10 and aconnecting rod 14 connects the wrist pin 13 with another wrist pin 15 onthe arm 16 secured to the outer end of the rod 8. As is apparent, therotation of the gear 10 will, through the medium of the connecting rod14 form a reciproeating motion to the said rod 8.

In practice the sand or gravel is delivered into the container 1 in anysuitable manner, and, with the agitation of the same by the action ofthe rod 8 and its teeth 9, it is continually delivered and distributedequally through the outlet space 17 between the lower side of the rod 8and the bottom of the container 1. This space 17 may be made larger orsmaller by the raising or lowering of the door plate 3 to which thebearings for the rod 8 are attached as noted above. This movement of thedoor plate 3 is accom plished by means of the following structure,namely:

Between the sides of the container 1 at the back thereof is secured anangle iron 18 between the sides of which are two or more nuts 19. At theupper edge of the door plate 3 are flanges 20. Turnable in each flange20 is a crank handle 21. Each crank handle 21 has a projecting threadedpin 22 thereon, which pins 22 are threaded through the nuts 19. Thuswith the turning of the crank handles 21 these threaded pins 22 Willadvance through the nuts 19 in one direction or the other. The crankhandles 21 have no vertical movement through the flanges 20 and hence asthe said pins 22 advance through the nuts 19, the door plate 3 Will beraised or lowered which will increase or diminish the size of the space17. The bearing members 6 during this operation move through-the slots 7From the foregoing description it can be readily ascertained that I haveproduced a very eiiicient and efiective spreader for sand and gravel andone Which can beqoperated automatically and easily by attaching it tothe rear end of a truck or Wagon carrying the material. The use of sucha spreader Will eliminate a lot of labor and expense incurred by theordinary method of spreading the material by hand from pilesor from avehicle.

From the foregoing description it Will also be readily seen that I haveproduced such a device as substantially fulfils the ole-- ject .of theinvention as set forth herein.

VVhile-this specification setsfort'h in de- Gopies of this patent may beobtained for tail the present and preferred construction of the device,still in practice such deviations from such detail may be resortedto asdo not form a departure 'from the spirit of the invention, as defined bythe appended claim.

Having thus described my invention What I claim as new and useful anddesire to secure by Letters Patent is:

A spreader-comprising a container having its rear end open, a verticaldoor plate adjustably and slidably mounted in said open end, downwardlyprojecting bearings fixed at the sides of the door plate and movabletherewith, a shaker rod arranged vfor reciprocating motion intheabearings immed'i ately under the door plate and adapted to bearagainst the bottom of the container when the door is at its .dotwnmostposit-ion, means for reciprocating said shaker rod and teeth on theshaker rod projecting horizontally into the container.

In testimony whereof-I afiix my signa- V ture.
